1. Lubricate the sliding surfaces for the bearing blocks
along the full length of the channels as shown in
FIGURE 19. Apply lubricant only to the indicated sur-
faces.
NOTE: The load rollers and sheaves have sealed bear-
ings and do not need additional lubrication.
2. Lubricate the pivot pins for the mast at the grease fit-
tings on the pivot pins. Use multi–purpose grease.

3. Lubricate the pivot pins for the tilt cylinders. There is
a grease fitting on each pivot pin. Use multi–purpose
grease.
4. If a side–shift carriage is installed, lubricate the fit-
tings and the sliding surfaces with multi–purpose
grease.
EMPTY CONTAINER ATTACHMENT
(See FIGURE 3.)
1. Lubricate the grease fittings for the side–shift rollers
and the anchor pins for the side–shift cylinder. Lubricate
the grease fittings for the lock pins. These fittings are lo-
cated at the top of the end beams.
2. Lubricate the sliding surfaces for all of the bearing
blocks.
3. Remove the drain plugs at the bottom of both end
beams to drain moisture from the accumulators.
GENERAL LUBRICATION
Inspect all hinges, pins, linkages, cables, pedals and lev-
ers for wear and damage. Lubricate these parts as neces-
sary with engine oil.
FORKS, CHECK FOR WEAR AND
DAMAGE (See FIGURE 5.)
WARNING
Never repair damaged forks. Do not heat, weld, or
bend the forks. Forks are made of special steel using
special methods. Replace damaged forks.
1. Check the heel and attachment points of the forks with
a penetrant or magnetic particle inspection.
2. Measure the thickness of the forks at a vertical section
where there is no wear. This is dimension X. Now meas-
ure the thickness at the heel (5) of the fork. If the thick-
ness is not more than 90% of dimension X, replace the
fork.
LIFT CHAINS, CHECK FOR WEAR
(See FIGURE 20.)
If a section of chain is 3% longer than a similar section of
new chain, the chain is worn and must be replaced. Mea-
sure the chain for wear where it moves over the sheaves.
If a chain scale is available, check the lift chains as
shown in FIGURE 20. If a chain scale is not available,
measure 20 links of chain. Measure from the center of a
pin to the center of another pin 20 pitches away. Com-
pare the length with the chart in FIGURE 20. Replace
the chain if the length of 20 links of the worn section is
more than the WEAR LIMIT.
